Multi-db version 3.0.2 beta tests

Hi all

I'm doing some work on the multi-db plugin to:
a) make it's error reporting friendlier
b) making it more failover ready for sites with multiple servers / replication
c) fixing some little bugs people have come across

I have a few different approaches I can take with the rewrites so I'm going to release a couple and hopefully get your opinion on whether certain versions speed up / slow down your site, cause additional errors / remove any errors you have.

The first beta test is attached to this post, it is only the db.php file - you will need to already have / or set up a db-config.php file to test this (it is primarily for those who already have a multi-db set up and working configuration).

Just replace the db.php file here with the existing one and things should carry on working as before.

I got the following error when I upload your db php. And website has completely down.
Then I upload the normal db file it is ok again.

Warning: mysql_get_server_info(): supplied argument is not a valid MySQL-Link resource in /home/ra6org1/public_html/wp-content/db.php on line 656

Warning: Cannot modify header information - headers already sent by (output started at /home/ra6org1/public_html/wp-content/db.php:656) in /home/ra6org1/public_html/wp-includes/functions.php on line 3125

I also get the following error in admin area when I upload the neb db.php

Warning: mysql_get_server_info(): supplied argument is not a valid MySQL-Link resource in /home/ra6org1/public_html/wp-content/db.php on line 656

Can’t select database

We were able to connect to the database server (which means your username and password is okay) but not able to select the ra6org1_global database.

* Are you sure it exists?
* Does the user ra6org1_new have permission to use the ra6org1_global database?
* On some systems the name of your database is prefixed with your username, so it would be like username_ra6org1_global. Could that be the problem?

@turkon: I think it has something to do with the user 'ra6org1_new' not being able to access the database 'ra6org1_global'. Verify if that user is linked to that database, in your hosting control panel.

Just jumped into the membership with wpmudev. Running MS and the idea is to create a system whereby I can have a main wordpress site running and then replicate the other site using the network setup. What I am looking for is for a way to limit the pages the the sites have compared to the main site. Is this possible with your plugin?

This is extremely useful is you are running a membership site using WishList as the membership site plugin and then allowing people to sign up for a free, or premium membership. Once they do that we can either automatically create a blog site or manually create it but from within the MS Network I would like the ability to choose what content will appear on that site blog, (pages, posts, plugins, etc.)

I'm running it on Amazon EC2 (2 large servers with 7.5 gig of ram each). 4096 db and over 13,000 blogs so far. About to push it up over 50-60,000 in the next couple of months and so far it's running great.
